Symantec Security Response has developed a removal Tool to clean the infections of the following variants of the W32.Sasser Worm:
W32.Sasser.Worm
W32.Sasser.B.Worm
W32.Sasser.C.Worm
W32.Sasser.D
W32.Sasser.E.Worm
W32.Sasser.G
The W32.Sasser Family of worms can run on (but not infect) Windows 95/98/Me computers. Although these operating systems cannot be infected, they can still be used to infect vulnerable systems that they are able to connect to. In this case, the worm will waste a lot of resources so that programs cannot run properly, including our removal tool. (On Windows 95/98/Me computers, the tool should be run in Safe mode.)
Note: The execution of the worm causes LSASS.EXE to crash on some systems. The result of this is that the system may undergo a reboot. The fixtool can be successfully run only after the system has completed the reboot.
